Abstract:

Primary failure of eruption(PFE) is a rare condition in which tooth eruption failure occurs without obvious local or systemic causes.PFE can also be caused by a disturbance in the eruption mechanism. This condition often affects permanent molars and causes a severe posterior openbite. PFE diagnosis and treatment remain confronted by difficulties. This article reviews the PFE clinical manifestations, etiology, clinical diagnosis, and treatment modalities.

Key words: tooth eruption, primary failure of eruption, posterior openbite, parathyroid hormone receptor 1
